Specification of Letters Patent.

Patented July 14, 1914.

Application filed May 14, 19,13. Serial No. 767,635.

T 0 all uz om it may concern.'

Be it known that I, Encan 'J'.,Ricriannson a citizen of the United States, residing at ioux City, in the county of Woodbury and State of Iowa, have invented new and useful Improvements in Aut0mobile-Radi `ators, of-which the following` is a specification.

This invention provides a radiator for use in connection with internal combustion engines for cooling the water circulating through the jacket ofthe engine cylinder to prevent overheating. i .A

In its specific adaptation the invention provides a radiator for automobiles.I said radiator comprising means to prevent the chilling or freezing' of the water in extreme cold when the machine is at rest. l

A further purpose of the invention is the provision of a radiator which presents a maximum cooling surface for radiating lient in'warm weather, thereby preventing overheating of the water and the conversion of the same into steam. y'

The invention consists of the novel features, details of construction and combina- 'tion of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claim.

Referring to the' drawings, forming a part of the specication, Figure l'is a perspective view of an automobile radiator embodying' the invention. Fig. 2 -is a rear view.` Fig. 3 is a vertical central longitudinal section. Fig. 4 is a transverse section on the line 1/-1/ of Fig. 2. Fig.l is a horizontal section 'on the line.. :rri' of Fig. 2. Fig. is a front view, the easing being removed'. Fig. 7 is a rear view of part of the casing, showing more clearly the sliding sectional door for closing the opening in the front of the casing. Fig. 8 is a view of the radiator inverted, Fig. fi-is a detail section of the lower portion ofthe radiator showing thc front end of the doors dropped into vertical position.

CorrespondingY and like parts are referred to in the following description, and indicated in all the views of the drawings, by-

the same reference characters.

The radiator may be of any construction or design and comprises an upper water compartment 1, a lower water compartment 2 und intermediate tubes 3 connecting such compartments. Heat radiating tins 4 are interposed between the water tubes 3 and assist materially in cooling the water circulating through the tubes 3 when the radiator is in active operation.

A heating chamber 5 is located below the waterfeompartment 2 and is adapted to receive heating means of any nature to prevent the chilling or freezing of the water in cold weather. ln the preferable form the heater consists of two lamps 8 which are placed in opposite ends of the heating chamber 5 and secured' therein by any suitable means. .The heating chamber is closed at its front and bottom by means ofdoors T s and 8 which may be removable, the front door-7 being hinged to swing downward at its upper edge. The sides and bottom of the heating chamber are provided with openings for the ingress of air to support com hustion when the lamps 6 are lighted.

Air' tubes 9 extend' through the water tubes 3 and the water compartments l and 2 and connect with th'e outer walls thereof, as shown most clearly in Fig. 3. The lower ends of the air tubes 9 are spaced from the top-of the water compartment 2 and make close connection with the bottom of suoli compartment, thereby admitting of the watervcirculating from the compartment 2 through the water tubes. The upper ends of the air tubes 9 pass loosely through the 'bottom of the upper compartment l and ,malte close connection with the top of such compartment so as not to interfere with the circulation of the water between the compartmcnt l and water tubes 3. Other air tubes l0 and ll lead from the heating chamber 5, the air tubes 10 being.r at the sides of the radiator and having their upper ends opening through the top thereof. The in' termcdiate air tubes l1 connect at their upper ends with the air spaces l2 above the `water compartment l with which the upper ends of the air tubes D communicate. The filling tube 13 connects with a water space 14 located between thc air spaces 12. The walls inclosing the air spaces 12 are provided with openings for the escape of hot air. Plates `l5 close the' tops ofthe air .spaces 12 and are made removable to admit of access being had readily to such air spaces for any purpose. Coupling ends 16 communicarte with the air spaces 12 and are adapted to make connection with ipes or tubes leading to1 the 'space surrounding the carbureter to prevent chilling of the latter in cold l no .weather so that the enginemay be easily stafted. Other coupling ends 17 connect with the water compartments 1 and 2 and are adapted to have the pipes leading to the water jacket of the engine connected thereto.

A casing 18 incloses the main body of the radiator and is provided in its front with an 'opening opposite the space formed between the upper and lower water compartments so that air may pass freely throuwh the tubes and heat radiating fins. T e opening in the front of the easing is protected by means of a screen 19. In cold weather or when it is re. uired to retain the heat'the opening in the rout of the casing may be closed by sectional sliding doors 20 which are mounted in guides 21 arranged above and below the opening. The doors 20 are adapted to be secured either in closed or open position by means of knobs 22 which are threaded to stems attached to the outermost door sections, the stems of the knobs operating in a slot 23 formed in the screen 19. When the knobs 22 are loosened tho doors may be slid open or closed and are lield in the required. osition by tightening the knobs so as to clamp the part of the screen 19 adiacent' the slot 23 bet'n'een suoli knobs and'the outer door sections. Openings are formed in the side walls of the spaces formed above and below the water com artments 1 and 2 so that air may have uno structed passage. The casing 18 protects the main portion of the radiator and gives a finished appearance thereto. A door ,2L is p'rovded in the' lower portion of the front of the casin o posite the door 7 so that access may be ad) to the heating chainber for lightin or trimming the lam s. 'lhe casing is rca ily removable, therebg ihcilitating access to the main portion o' the radiator for repairs or other purpose. An overflow pipe 25 extends into the water space 14 so as to carry o excess of water or any vapor that may be enerated. A drain cock 2G connects with t ie lower portion of the water compartment 2 for drawing olf all water from the radiator when it is required to empty the saine.

In cold weather the water is prevented from chillingh and freezing in the radiator by lighting t e lamps 6 or havinpl recourse to the particular form of heater ocated in the heating chamber 5. The Warm airafter leaving the` heating chamber 5 passes upwardly through the air tubes 9, and 11, thereby warminfr the water. When the heating feature of lthe radiator is in active o eration vthe doors are closed as also t e doors 24 and 7. In warm weathervor when it is desirable to obtain a maximum amount of heat radiating surface the lamps are removed or the heater dispensed with, the doors 7 and. 8 being removed and the door 24 thrown open so that cool air may have an unobstructed passage through the air tubes, thereby supplementing the air passing upon the exterior of the water tubes and water compartments, with the result that the water is prevented from lieatin excessively. It is understood that the dgoors' 20 are slid into open osition so that the cool air may circulate reely through the water tubes and heat radiatin fins 4.

From the foregoing escription, taken in connection with the accompanying drawlngs. theadvanta es of the construction and of the method o operation will be readily apparent to those skilled in the art to whic the invention appertains, and while I have described the principle of operation of the i invention, together with the device which now consider to be the best embodiment thereof, I desire to have it understood that,

the device shown is merely illustrative, and that such changes may be made when de` sired as are within the scope of the claim ap )ended hereto.

aving thus described the invention what is claimed as new,` is

A radiator comprising upperand lower water compartments, intermediate water tubes connecting such compartments, a heating chamber beneath the lower'compartment having door covered openings in its front and bottom, an air space above the upper compartment, air tubes connecting the heating chamber and air space, a Casin inclosing the compartments and intermediate con nectin 'tubes, and a door in the lower portion o the front of the casin o posite the door opening in the :front4 ofi the heating chamber.

In testimony whereof I affix my signature in presence of two witnesses.
